Abstract:
A position pointer is provided for indicating a position on a sensor of a position detection device. The position pointer includes an elongate pointer body having a distal end and a proximal end; a first electrode disposed near the distal end; and a second electrode different from the first electrode and disposed near the distal end, wherein both the first and second electrodes are capacitively coupleable with the sensor of the position detection device. The position pointer includes a detection circuit configured to intermittently detect signals transmitted from the position detection device; a signal circuit configured to generate a position signal to be transmitted to the position detection device; and a transmission circuit configured to control transmission of the position signal. The transmission circuit, based on a detection result of the detection circuit, controls transmission of the position signal via the first electrode.
